Ropeless Fishing Shows Promise, But There’s a Catch: Financial, Safety, Technology Challenges

February 12, 2021 — The lobster industry could be getting a new sound.

On a cold January morning, a lobster trap sitting on a table at a manufacturing facility in Wareham is rhythmically beeping. Two final beeps have a special meaning.

“So that’s the release confirmation,” explained Rob Morris, who sells acoustic release systems for the underwater technology company EdgeTech.

With this technology, lobstermen can send the acoustic signal from a phone app to a trap on the ocean floor. The signal triggers an airbag, with a line attached, to launch up to the surface, allowing the traps to be hauled in. These “ropeless” systems do away with the high number of vertical lines that run from buoys on the surface down to traps on the ocean floor.

Looking at this table, Morris sees the future of the fishery – and many conservationists share that hope. Ropeless fishing eliminates vertical lines in the water column that are blamed for around half of all reported North Atlantic right whale deaths.

But experts say the transition to ropeless is moving too slowly. By the time working gear can get into the boats of thousands of lobstermen across New England, it may be too late to save critically endangered right whales.

It’s being held up by technical, regulatory, and financial factors.

Massachusetts launches ropeless gear study

January 22, 2021 — A year-long feasibility study to assess using ropeless trap gear in the New England lobster fishery has been launched by the Massachusetts Division of Marine Fisheries.

Funded in part by the National Fish and Wildlife Foundation in partnership with NOAA, the “accelerated timeline” project “will interview dozens of fishermen, technologists, policy experts, and scientists to fully evaluate the challenges and opportunities of the new gear type,” the state agency said in a Jan. 21 statement.

Ropeless gear – sometimes known as pop-up gear, or as Massachusetts officials call it, on-call gear – are designs that seek to replace the traditional floating buoy line gear used in lobster, crab and fish trap fisheries.

There’s high interest in these alternatives as a potential solution to prevent marine mammal entanglements in gear – especially the highly endangered northern right whale, with an East Coast population now estimated to be less than 400 animals.
